' tions for internal combustion engines, and

my invention aims to furnish a multi-cylinder internal combustion engine with novel rotary .intake and exhaust valves which obviate a '.fiultiplicity' of' ports, permit of proper lubrication, and assure compactness,

ease of operation, and proper` cooling of thosev parts subjected to heat from the cylinders of the engine. A

My invention further aimsto; provide an internal combustion engine having vcylinders en 620e withintegral valve housings and horizontal. partitions c operating with an engine casing informingan intake chamber and an exhaust manifold, the disposal of said chamber and said manifold being such that vertically disposed rotary Valves, each having a common intake and exhaust port,

can be advantageously used and driven in synclironisin and. in timed relation to the usual operation of a multi-cylinder engine.

M invention further aims to provide a' nove system of lubrication and packing for an engine in accordance with this invention', and inthe general make-up ot' the engine, the parts are constructed withy a View of reducl ing-the cost of manufacture and at the same assembling. `view the invention resides in the novel construction, combination and arrangement of .parts to be hereinafter specifically described and :then claimed.

timeV insure safety, durability and ease of lVith these and other ends in -Refereiice will now be had to the drawing, wherein* y Figure l is a horizontal sectional view of Athe internal combustion engine, showing a gearl chamber and an intake chamber; Fig. 2 isa side elevation of a portion of the engine, partly broken away and partly in vertical section, sliowingthe line Il on which the Fig. 1 view is taken; Fig. 3 is an enlarged elevation of a detached rotary valve, partly broken away and partly in-section; Fig. 4 is a vertical cross sectional view of a portion ot' the engine; Fig. 5 is a perspective View of detached packingring; is a vertical sectional view of detached coinbined cup and bearing.

Inl the drawing, 1 .denotesaplurality-of cylinders cast en bloc with the upper ends thereof provided with necks 2 and cylindrical valve housings.3, said necks establishing communication between the cylinders and the housings. The cylinders 1, at the upper vends thereof, supporta horizontal partition or wall 4 andthe valve housings 3 are connected by a horizontal partition or wall 5 and this wall is connected? to V*he upper end jof the cylinders by a "longitudinal vertically disposeddividing wall 6. The walls 4, 5 and 6 are connectedl to an engine casing 7 and said casing coperates with said wall in providinga water jacket 8 for the cylinders 1 and an intake chamber 9 at one side of the engine. At the opposite side ofthe engine the casing 7 is formed with an eX- haust manifold 10 having angularly disposed and curved branches 11 in communication with valve housings 3 of the cylinders 1. By comparing Figs. 1 and 4, it will rateiitea nee. ia, reis.

be observed that the wall 4 simply forms the l bottom of the intake chamber 9, and on the exhaust side of the engine, the jacket 8 eX- tends around branches of the manifold 10.

.The casing 7 is providedwith an intake port 12 communicating with the chamber 9 and this chamber communicatesv with the housings 3 through intake ports 13 provided therefor in said housings.

Rotatable in each valve housing 3 is a rotary hollow vertically disposed valve 14 trudes from. below the end thereof to 4eX- tend into the neck 2 of the cylinder while the opposite end of the elbow opens in an annular packing seat 16 in, the periphery of the valve. The seat 16 accommodates a resilient packing ring 17 approximately the The upper end of each hollow rotary valve is formed with a horizontally disposed gear formed with an elbow 15, one endof which l ,opens axially of the rotary valve and pro- 'wheel :2i and the gear Wheels of seid rotary Afaives are adapted to mesh within ay gear hamber 92 torn'ied bythe iwali 5 and the engine ces-.ing "L denier-fed hub portion provided'ivith a oountersuni; bearing; block and surround# 'i fr said hearing: bioch is animieren :range forn'iing; basin on to@ The bottom ot the basin 255 port y communicating with the inof the rotary mire, and the side Welt d voire at the bottom. thereof, has en port fiwhereby inhricant may enter salive housings 3 and necks 2 and innon.itricticuiai rotation vet the rotary veives in the housingss 3 `when motion is inito the trel et gears 2i.
